BS EN 1838:2013 Emergency Lighting Testing

First of all, What is BS EN 1838:2013 standard? This standard states general rules for emergency escape lighting and standby lighting systems installed in an office, property, site, building or working place where such systems are required. These areas are predominantly where the public or workers have access.

Use of BS EN 1838 can help save life and unnecessary anxiety and confusion can be alleviated by strategically placed visible signs indicating the way out of a location.

Types of emergency lighting at a location with the objective :

S.No

Type of lightning

Objective

1

Emergency lighting

to ensure the safety lighting is provided on the dot in a specified area when the normal mains power supply to the usual lighting installation fails.

2

Emergency Escape lightning

to enable a safe exit from a location and/or building in the event of failure of the mains’ normal supply

3

Emergency Escape route lightning

to enable the safe exit from a location or building for occupants by providing appropriate visual conditions and direction finding on escape routes, and in special locations, and to ensure that firefighting and safety equipment can be readily located and used.

to the safety of people involved in a potentially dangerous process or situation and to enable proper shutdown procedures to be carried out for the safety of other occupants of the location or the building.

7. Coordination/interface with luminaire manufacturers where main luminaires are to be converted into emergency lighting luminaires

8. Discover the exit sign requirements

9. Find any high-risk areas

10. Open areas larger than 60m² floor areas need to be identified

11. Need for external illumination outside final exit doors and on a route to a place of safety.

Locations :

It is paramount that the emergency luminaires are placed to give suitable illuminance in the event of a failure of the normal lighting.

S.no

Area

Details

1

Open Area

Open areas are often called anti-panic lighting. These are areas larger than 60m² floor area or maybe areas identified by the fire risk assessment as requiring safety illumination

2

Emergency Exit and escape route

Emergency exits and escape routes should be provided with signs

3

External areas in the immediate vicinity of exits

In order to assist dispersal to a place of safety, the external areas in the immediate vicinity of final exits should be illuminated in accordance with the illumination level for escape routes, given in EN 1838 (BS 5266-7) of not less than 1 Lux

4

Lift cars

Lift present a problem because the experience of being confined in the dark within a small space for an indefinite period of time is not only unpleasant but may cause harm to those who are nervous or suffer from claustrophobia

5

Moving stairways and walkways

Moving stairways and walkways should be illuminated as if they were part of an escape route in the event of mains failure.

6

Toilet Facilities

Toilet facilities exceeding 8 metres squared gross area should be provided with emergency lighting as if they were open areas.

7

Switch rooms and plant rooms

Emergency lighting should be provided in all motor generator rooms, control rooms, plant rooms, switch rooms and adjacent to main switchgear or control equipment associated with the provision of normal and emergency lighting to the premises.

8

Covered car parks

The pedestrian escape routes from covered and multi-storey car parks should be provided with emergency lighting.

Duration of battery backup:

The battery back-up of the emergency lighting system will depend on the use of the building and the evacuation strategy. 3-hour duration is required in places of entertainment (cinemas, theatres, etc) and for buildings that have a sleeping risk (hotels and guesthouses, etc.).

Lumination Levels

The level of illuminance required depends on the function of an area.

Certain specific locations require a specific illuminance and response time the below table gives the locations and response time.
